Hi ancy chacko.
try this code,

string path = string.Concat((Server.MapPath("~/admin/Import/" + FileUpload.FileName)));

                FileUpload.PostedFile.SaveAs(path);

                string FileExt = System.IO.Path.GetExtension(FileUpload.FileName);

                OleDbConnection OleDbcon = new OleDbConnection();

                OleDbcon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;");

                OleDbcon.Open();

                OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", OleDbcon);

                OleDbDataAdapter objAdapter1 = new OleDbDataAdapter(cmd);


                conn.Open();

                DbDataReader dr = cmd.ExecuteReader();

                dt.Load(dr);
 if (dt.Rows.Count > 0)
                {
                    for (int i = 0; i < dt.Rows.Count; i++)
                    {
//do stuff here like upload data one by one
}
//call here your bind gridview function

}
